# Evolution of the coupling constant in SU(2) lattice gauge theory with two adjoint fermions

@article{Hietanen2009EvolutionOT, title={Evolution of the coupling constant in SU(2) lattice gauge theory with two adjoint fermions}, author={Ari J. Hietanen and Kari Rummukainen and Kimmo Tuominen Florida International University and University of Helsinki and University of Oulu and University of Jyvaskyla}, journal={Physical Review D}, year={2009}, volume={80}, pages={094504} }

We measure the evolution of the coupling constant using the Schroedinger functional method in the lattice formulation of SU(2) gauge theory with two massless Dirac fermions in the adjoint representation. We observe strong evidence for an infrared fixed point, where the theory becomes conformal. We measure the {beta} function and the coupling constant as a function of the energy sca0008.
